Ask Dr. Z

Dear Dr. Z, Thank you for taking the time to consider my question. Our facility treated a patient who they suspected as having Brugaga Syndrome so a flecainide challenge was done. The patient had a base EKG done then was given 400mg of oral flecainide. EKG’s were then done after one half hour, one hour, two hours, three hours and four hours. My question is what CPT code (if any) would be appropriate for this procedure? I have reviewed the Noninvasive Physiologic Studies and Procedure section of the CPT book and 93799 – unlisted cardiovascular service or procedure is the only one I feel can be used. The other option I have considered is to only code the EKG’s and not apply a code for “flecainide challenge”. Thank you in advance for your input. Debra Patterson, RHIT
